Description

Ideally suited for read-heavy workloads. One node (Leader) handles writes, others (Followers) replicate data and handle reads.

Where to use

• Databases (Postgres, MySQL).

Real World Example

Primary DB accepts writes, replicas serve read traffic.

Code Example

class Leader–Follower:
    def __init__(self):
        pass

    def execute(self):
        print('Executing Leader–Follower')
